f Another and equally important ob ectpf the invention is to provide thegate with novelly constructed and "ar1'angecl trips which, when engagedby the'wheels of rolling stock, will serve toniove the V gate to openedand closedlpositions The invention consists, furthermore, in thenovelarrangements and combinations of the'partsof the gate, as wellasfin the details of the construction of the same, all of which iwillbemore fully described in the following specification and'then finally em:

posed 'bolts 3, which as will be noted, serve to pivotally support theusual cross arms 4: and 4, the rear ends of which are weighted as at 5in order that the same will normally assume their open or substantiallyupright positions. It of course will be noted, that the arms 4 aremounted off-center, the longer portions thereof being of lengthssufli'cient "to span the space between the spaced uprights 1. and 2.Brackets 6 are secured to certain of the sides of the uprights 1 an'd2and serve to receivethe oppositely disposed free endsof the arms 1, thusaffording an efi'ectu-al stop therefor whereby to limit the downwardmovement of the same and alsoefl'ectually bracing the same. fPulleysindicated by the numerals 7 and 8 are supportedin the lower portionsofthe several hollow uprights 1 and 2 adjacent slots 9 and 10formedtherein, in order that cables, hereinafter described, may bepassedthereoven Spaced gate actuating trips 11 and 12 are pivotedto the sides'of one of' the rails of the track T asat-13 and have their upperportions formed substantially V-shaped, While the lower'portions thereofare bent downward for connection with the arm closing cables 14 and15,through contractile coil springs 16., As will be noted, these closingcables 14: and 15 are'passed over spaced pulleys '17 supported uponsuitable brackets arranged in, proximity to the roadway and track andare connected with thegate arms 4 and 4, respectively. Spring arms 18haV-f ing certain of their ends bent upwardly as at 19 are positionedadjacent the lower ends of the trips 11 and*12 and are adapted to beengaged therewith subsequently to the y de- Ipressingoftlie trips byengagement ofthe wheels of the rolling stock therewith. In this way, itwill be readily understood that the trips 11 and 12 when once depressedwill be maintained in such positions until released, by meanshereinafter described. Releasing cables 20 and 21 are connected to thearms 4 and 4: respectively, and extend downwardly through the hollowuprights 1 and 2 over pulleys 8 and about other pulleys 22 havingconnection with the ends of the oil"- set portions 19 of the spring arms18. Hence, when the trip 11 is depressed by the wheels of the rollingstock passing thereover, the same will act through the closing cable 14to cause the closing of the arm 4: supported on the upright 1. As therolling stock proceeds over the-track T, the wheels thereof will beengaged with the second or positionby, meansof the cable 15.v Simuhtaneously with the closingof the arm 4, the

. first arm 4 will be permitted. to .movcia-toitsi open position, sincethe arm 4 will impart a, pull to the releasing cable-21', thus disenrgaging the end port-i0na19' of thearm 18 from the lowerwendflof, thetrip 11. (Dbviously, this operation is: reversed when the trip 12,is-first depressed. v

Qther trips 23 and24-are pivotally mount:- ed on the rail of the; trackT carrying; the trips 11 and 12, ,at points vdistant; therefrom andhave'their upper portions formed substantially V-shaped while the lower!ends are bent; downwardly and engaged by short releasing; cables 25. and26, which as will be noted,v are extended into engagement with theangular ends 19 of the arms18. The releasing}; cables 20 and 26 are,-extended through a. guide 20 arranged adjacentthe trip 12 and the cables21 and, 25 are, extended through a guide 21?" arranged ad.- jacenttheltrip 11. The rolling; stockv upon proceeding farther over the trackT will engage either one: of, the tripss23; 01224:, depressing the sameand causing t.heend,,1:9 of the spring arm.18.connectedtherctoto bemoved OlllJ'Ofi engagement with itsrespective end of the trip, 11 or 12,thereby releasing saidtrips and permittingthe arms 4 con nectedtheretoto be immediately moved to their upperor-o-pen positions. I

From the foregoing, it-is believed that a full understanding of theconstruction and operationof my improved gate is afforded. However, inthis connection, it, is to be noted that the spring 16 serves to,prevent. the transmissionrofexcessive vibration, or, abnormal strainstothe cables 14, and 15. and to thepivoted arms 4 connected thereto;Further, it is to-be alsounderstood that the pulleys 7 and 8 maybe of:the double sheave type, if desired,thus rendering the construction morecompact.

The various trips 11,12, 23"and 24 may be arrangedcn the track T at anydesirable distance apart, such as conditions or preference may dictate,providing that su lGient space is afi'orded to insure properfunctioning: of the-same:- during; the passage of the rolling stockthereoven Manifestly, the construction shown is 0e.- pableofl'considerable modification and such modification; as is; Within; thescope. of my c1aims,\I,1 consider within, the spiritof; my invention: YI i lhclaimr,
